1 Answer I have a 7683 autosampler on GC-MS and GC-FID instruments. They are about 15 years old. Recently, both autosamplers stopped working. Once an analysis is initiated, the carosel does its thing spinning around, the syringe mechanism lowers to the waste vial, and then it stops. It cannot seem to raise up or complete the injection. Any idea what is wrong?

0 Answers after a power supply off in our building, the HPLC went on again. But now it is impossible to relaunch Labsolution. Everything is ok on the HPLC and on the local network. But a message such as this appears "error 109: labsolution was not lauunched". We put the PC off and on (the HPLC too). Nothing changes? Any ideas? I have a 80 vials batch to pass!!!! Help!

0 Answers The auto sampler and the furnace initiate without issue. The spectrophotometer will not power up and doesn't see the installed deuterium lamp either.

3 AnswersWe have two Varian CP-3800 GC units. In the analysis* with TSD (GC1) and TSD or FID (GC2) both chromatographs show a progressive reduction of signal in the detection of nicotine during the day (for example, using TSD in a day the initial ABC is 1000 in the morning and the final ABC is 800-900 in the afternoon). Because both chromatographs are showing the same problem and share the main gas supply lines, we verify and there are no gas leaks.*Using very similar methods: same capillary column type, program temperature, standard solution (fresh or old), solvent, etc.

Does anyone know why this is happening?
